Year-Round Comfort: Fully insulated and fitted with heating and electrics, our annexes are warm and comfortable whatever the season.
Quick & Cost-Effective Alternative: Avoid the time, disruption, and expense of traditional home extensions with garden annexes. Quicker to install and highly efficient.
Increase Property Value: A well-designed garden annexe adds lasting appeal and usable space, making your home more attractive to future buyers
What is a Good Size for a Garden Annex?
The size of your garden annexe depends on its purpose and available space. Most clients choose sizes between 3m x 4m and 5m x 6m, which can comfortably accommodate a bedroom, bathroom, and seating or kitchenette area. Larger annexes provide room for multiple bedrooms or more generous living space, giving flexibility for long-term use or multiple occupants.
If you’re unsure what size fits your garden or needs, our team can assess your space and help you plan the ideal layout, including guidance on planning requirements where applicable. For full costs by garden room size, download our Pricing Brochure now!
